That's a good question. How does Windows handle this, by the way?

It's just an idea, but would it be possible to make the name resolv 
order changeable from the outside, i.e. as part of the public API? 
Then gvfs/nautilus, when the first attempt to resolve the hostname 
with the default order lead to a bogus IP from which it was impossible 
to receive a share list, could try a second time with precedence on 
"bcast" before they finally give up and show an error message.

To be honest, I don't know. I do not even know if my router is able to 
distinguish between local and non-local DNs queries. At least I have 
not found any setting to change this behaviour in its preferences.
